ORIGINAL
Name of Applicant: Chien-Chung Hu Actual Inventor: Chien-Chung Hu Address for Service: MADDERNS, 1st Floor, 64 Hindmarsh Square, Adelaide, South Australia, Australia Invention title: FOAM RUBBER SHEET WITH EMBOSSES ON BOTH SIDES THEREOF The following statement is a full description of this invention, including the best method of performing it known to me.
I PatAU132) The present invention relates to a foam rubber sheet with embosses on both sides thereof.
Materials for clothes include cotton, hemp, flax, silk, etc. A neoprene sheet having a sealing effect is used to produce clothes with anti-cold, waterproof, and warm-keeping functions for diving, surfing, fishing, sporting, etc. The neoprene sheet can also be used to produce medically protective instruments such as waistbands, kneepads, etc.
Fig. 4 of the drawings illustrates a conventional foam rubber sheet having a substrate made from foam rubber material and two cloth layers 60 bonded to both sides of the substrate 50, respectively. The substrate 50 is generally made from neoprene to provide required softness and tensile elasticity for producing clothes with anti-cold, waterproof, and warmkeeping functions. However, it was found that the wearer felt uncomfortable after a period of time due to the waterproof and airtight effects of the clothes. In addition, the surfaces of the clothes made from the foam rubber sheet cannot provide a three-dimensional appearance.
5 Fig. 5 illustrates a conventional foam rubber sheet 7 having a substrate 70 made from foam rubber material and two cloth layers 80 and 81 bonded to both sides of the substrate respectively. An outer surface of one of the cloth layers, layer 81 is embossed to provide a three-dimensional pattern 82 for aesthetic purpose. However, the outer surface of the other cloth layer 80 that is in contact with the skin of the wearer is still planar. As a result, uncomfortable feeling of the wearer resulting from air-impermeability of air still exists.
Currently in the art, the foam rubber sheet 7 is punched by a die (not shown) with a specific pattern to form the pattern 82 on a side of the foam rubber sheet 7. Such a process has a limit in the area of the foam rubber sheet 7 to be punched in each punching process by the die. In addition, the foam rubber sheet 7 cannot be processed continuously and rapidly to have desired emboss on a side thereof.
It is the primary object of the present invention to provide a foam rubber sheet with embosses on both sides thereof The foam rubber sheet with embosses on both sides thereof can be produced continuously and quickly.
A foam rubber sheet in accordance with the present invention comprises a substrate made from rubber material and two cloth layers respectively bonded to two sides of the substrate. Each cloth layer has an outer surface comprising a plurality of recessed portions and a plurality of protruded portions.
In the drawings: Fig. 1 is a perspective view of a foam rubber sheet in accordance with the present invention ~Fig. 2 is a schematic view illustrating formation of embosses on both sides of the foam rubber sheet in accordance with the present invention Fig. 2A is an enlarged view of a oircle in Fig. 2.
Fig. 3 is a partial sectional view of the foam rubber sheet in accordance with the present 15 invention Fig. 4 is a partial sectional view ofa conventional foam rubber sheet.
Fig. 5 is a partial sectional view of another conventional foam rubber sheet.
Referring to Figs. 1 through 3, a foam rubber sheet 1 in accordance with the present invention generally is made from a foam rubber sheet raw material 30 having a substrate 10 and two cloth layers 20 bonded on both sides thereof The foam rubber sheet raw material wound around a bobbin 32 is drawn by a pair of embossing rolls 40 to pass through the embossing rolls 40. Each embossing roll 40 has an outer surface with a desired pattern 41 thereon.
The cloth layers 20 on the foam rubber sheet raw material 30 is heat-pressed by the embossing rolls 40 when the foam rubber sheet raw material 30 is passing through the pair of embossing rolls 40. Protruded portions 41b (Fig. 2a) on the pattern 41"of each embossing roll squeeze the material of the cloth layer 20 into the substrate 10, thereby generating recessed portions 212 in the substrate 10. In addition, the material of the substrate 10 is forced to enter recessed portions 41b (Fig. 2a) of the pattern 41 on the respective roll 40 and thus squeezes the material of the cloth layer 20 to protrude outward, thereby forming protruded portions 211 on each cloth layer 20. Thus, each cloth layer 20 has a plurality of recessed portions 212 and a plurality of protruded portions 211 on an outer surface thereof after the foam rubber sheet raw material 30 has passed through the pair of embossing rolls 40, as shown in Figs. 2 and 2A_ The foam rubber sheet material 30 becomes a foam rubber sheet 1 with a desired pattern on each of two sides thereof each side of the foam rubber sheet 1 is embossed by a respective embossing roll 40. The foam rubber sheet 1 is then guided by a roller 42 to a package winding fixture (not shown) or the like.
As illustrated in Fig. 3, the foam rubber sheet 1 have recessed portions 212 on each side thereof which may provide spaces for air. Thus, the wearer will not feel uncomfortable in the skin that is in contact with the foam rubber sheet 1 even after a long-term wearing. At least some of the recessed portions 212 are communicated with each other. The substrate 10 of the S. 015 foam rubber sheet 1 is made from rubber material, preferably neoprene, to provide desired softness, sealing effect, and tensile elasticity. The foam rubber sheet 1 can thus be used to produce cloths with anti-cold, waterproof, and warm-keeping functions. Another advantage provided by the patterns on both sides of the foam rubber sheet 1 is, of course, the aesthetically pleasing effect. Clothes made from the foam rubber sheet 1 can be worn with either side facing outward. In addition, the foam rubber sheet 1 can be produced continuously and rapidly.

Claims (4)
